To all whom it may concern: I

Be it "known that l, VVELHNGTQN ll. GRA- HAM a citizen of the United States, residin .at- Brooklyn, in the county of. Klngs an State of New York, have invented certaln new and" useful Improvements in Motor- Hangers; and I do hereby declare the following to be a' full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

This invention relates to new. and useful improvements in motor hangers and the principal object of the inventlon is to providea device for use in supporting the driving motors of aimotor. vehicle so as to eliminate the necessity of using the ordinary universal joint and propeller shalt'between the motor'and the drive axle.

Another object of the invention is to'provide' a device which will flexibly supportthe' 3 motor in lace so as to'allow for free movejment or t e axle and, yet enable the device 'to be directly connected to the difl'erential gearing. 1 t I A further object of the invention is to provide a device which issu'pported in such position as who readily removed for makingrepairs and the like.

With these and'other objects inview, the invention.,-consists in the novel combination nd 'arrangementof parts which will'he fully-set forth in the'following specification and accompanying drawings, in which 2- lFigurel is a longitudmal sectlonalview througha motor vehicle, showing this deg vice as it would a pear whenapplied'thereto; Fig. 2 is an en" view of F g. l lllustrating 'in detail, the hanger;

Thisbar extends to'the opposite side bar of the chassis- 1 designates one i of the side bars of a chai's having connected not shown and forms the support for the hanger which will be more fullyhereinalter described. The sprin of the chassis is designatedby the numera 3 and is composed of lamlnatlons of the usual construction. The

It will be understood that t e seat is rockabl mounted on the axlehousing so as to al ow the free movement of the spring.

A presser blpck 24 is arranged in the aperture 24 and is retainedin inwardly extended position, by a spring 25. The inner ide of the wall of the cap ;immediately adjacent the threaded opening 24 is recessed,

as at26, to form a pocket in-which the lubri cant is retained.

Fitted into the cap previously described and resting on the inner face of the socket .20 in the saddle in place.

he saddle above referred to comprises an is-the hanger ball, designated by the 15 numeral 27 which is rovided with a re? duced neck 28 and rovided at its lower end. with a flange '29 aving projecting down-' wardly therefrom a stud 30, the lower end of which is formed with a flange31 for retainarcuatebody designated -generically by thd posite side of suitable bolts, or other fastening means 37,

to the plate 34 hereinbefore described, thus forming an encircling member around the" stud 30, which swivelly supports a;yoke 32 '33 of the in place. Thebnds'of the arms yoke 32"arefor'med with'hub ortions 38,- which are formed with enlarged ores 39; ex

i tending transverselytherethrough and, slots run which in turn'run in a on 40 which lead from the bore to th'e outer side ofthe hub; The width of the slots 40 is less than the diameter of the bores 39 for a purpose which will' be more fully hereinafter described.

Extending beneath, the motor 41 is the supporting, saddle 42 which consists f .an. arcuate body'forme'd .at the endof its arms withenlarged platesr'43 having thestuds 44 formed thereon. The studs 44'a re of a di- .ameter equal to the width of the slots40 in :arms of the saddle 42 and the endsof the when the dev ce is in assembled posit'on will pro3ect throughthe openings 39in t e"hubs the motor.

the invention. The armsof the saddle are preferably bolted, as at 47, to the motor 41 thus firmly supporting the motor in place.

Surroundin the rear end of the motor is a band 48 WhlCh is formed integrally with the housing 49 which is provided with an enlarged opening housing 51 is housing 49 and surrounds the opening 50 and the rear endof the housing 51 is provided with'an off-setportion 52 having formed thereon a flange 53 which surrounds the forward end of the differential housing '5. The motor shaft 54 extends into the housing 51 and is providedfwith a herringbone pinion 55 which meshes with a herringbone gear 56 mounted on the drive shaft 57 the rear end of which carries a beveled pinion 58 for meshing engagement with the 'beveled gear 6 of the. differential housing 5.

The shaft. 57 is journaled in suitable antifriction bearings carried by the housing 51 which will be more fully hereinafter described. The housing 51 above referred to is provided with a front wall 58 provided with a hollow boss, 59 arranged in'axial' aline- 50 in 1ts rear wall. A I secured to the rear face of the.

ment with relation to the shaft 57. An opening. 60 is formed in the wall 58 in alinement with the shaft.57 and accommodates the, forward end thereof. A suitable cup '61 is mounted in the boss 59 while a similar cup 62 is mounted on the forward end of the shaft 57 and bearing balls 63 run between the'cups as will be clearly seen upon reference to Fig.1. The opposite end of the shaft adgacent the beveled pinion 58 carries a cup 64 in which suitable bearing balls 65 p 66 which is secured in thehub portions 6 .wall 68 of the housing 51. In this way it wi 1 be seen that the friction of theshaft 57 is reduced'to a niimmum.

It willbe-apparent, from the foregoing that the use ofa device of this character will avoid'the necessity of providing a universal joint between the propeller shaft and the motor and between the propeller shaft and differential gear. It will also avoid the necessity of using 'the usual radius rods and "willmount the motor in such position as' to be readily movable with the rear axle and lyet allow for a direct drive of the axle from When the rear axle movestupwardly ia'will be seen that the motor W111 of the rear p5 38 In order toihold the studs in place a be rocked on the trunnions 44 and any'forisu ta-ble removable bushing '45 is provided ward, rearward" or side movement of the the inner. brnfe of which receives the studs rear axle will be permitted by the balland 44 whflethe periphery fits the opening 39 of socket joint.

The outer terminals of the'studs are headed and engaged with presser blocks 75 and expansion springs 76 are confined between the tops andbottoms of the housings and the presser blocks to resilientlylretain the studs in a position intermediate the ends of the housing, andthus' permit vertical movement of the axle and motorwith relation to the yoke .70 and vehicle frame against the tension of the springs 76. I c

In bothtypes ofthe invention, the pull exerted by the pinion-.58 upon the difi'eren tial gear 6, during the forward movement of the vehicle, 'efiects an. upward push on the motor, thereby relieving the cross bar 2 of considerable strain.

2. The combination with a chassis, of a yoke comprising an arcuate body, a universal connection between the center of the'arcurate body and the chassis, an arcuate sad-- dle, a motor adapted to fit in the saddle,
